SANITARY DISPLAY CABINET.

Specification of Letters Patent.

Patented Mar. 16, 1920.

To all whom it may concern:

Be it known that I, WALTER W. SLADE, a citizen of the United States, and a resident of Brookline, Massachusetts, whose post-office address is No. 403 Washington street, Boston, Massachusetts, have invented an Improvement in Sanitary Display-Cabinets, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

The present invention relates to sanitary cabinets and more particularly to a sanitary display or Work cabinet, in whicharticles are held in a movable frame within the cabinet, which framemay be swung entirely out of the cabinet when it is desired to inspect 01' handle the articles.

At the present time certain articles, as optical lenses, surgical instruments, razors, etc., that are used by, or otherwise brought into contact with, many different persons, are usually kept in sanitary display cabinets or closets when not in use. Heretofore it has been customary to have such articles on racks or shelves, which necessarily have to be re moved bodily from the sanitary display cabinet and placed on a bench or table when it is desired to use the same. of handling is undesirable and objectionable both from a utilitarian and sanitary standpoint, as it has been'found that the persons using the articles frequently leave the same out of the sanitary display cabinet during working hours, only returning same at the end of the day. Racks permanently attached within the sanitary display cabinet are objectionable also, as while such racks are sanitary in themselves, the temptation to remove the articles from the sanitary display cabinet and leave the same out during working hours is too great to be resisted.

Many articles, similar to those enumerated above, are arranged in cases for display, in order to more readily effect a sale thereof. Where such articles are handled and inspected by the customer as well as the salesman, the maintaining of the articles in sanitary condition at all times is practically impossble with former typesof cabinets. With the present invention, I am enabled to maintain such articles in a sterile condition at all times, as well as to display the articles for sale.

The princlpal object of my invention therefore, is an improved sanitary display Such a method cabinet in which articles may be arranged in a frame normally located within the cabinet,

and which ma be readily swung out of the cabinet when 1t is desired to use or inspect the articles.

Another object of my invention is the provision of an article holding display frame and mounting means therefor, which is nor mally placed within a sanitary cabinet, and which may be swung bodilyon its mounting to a position exterior of the cabinet, coming in the cabinet, and in dotted lines, the position of the frame exterior of the cabinet.

Referring to the drawing, 10.designates the sanitary display cabinet comprising the base 11, top 12, back 13, and members 14 and swinging doors 15. Preferably the doors 15 are inset with glass 19, and I may also make the ends and back of skeleton frames and inset them with glass, though such construction is optionable. The cabinet rests on a base or table comprising a top 16 and legs 17, the legs being of any suitable or desired length. I prefer to place the cabinet 10 on the table in the position shown in Fig. 2, and place a glass plate 18 on the table in front of the cabinet. The cabinet may be made of any suitable material, though for sanitary reasons I prefer to use pressed steel.

On the inside of the ends 14, or where the ends are inset with glass, on the frames thereof, are screwed, or otherwise fastened, brackets 20 and 30.

Pivotally mounted in the brackets 20 and 30 at 21 is a frame 22, at the upper ends of the arms 23 of which is pivotally mounted the frame members 24, these frame members being fastened together to form a unitary structure by the tie rods 25 and 26. Arms or links 27 and 28, pivotally mounted at their lower ends to the brackets 20 and 30 respectively, have a pivotal engagement at their upper ends with the frame members 24,

this connection being such that the links 27 and 28 are parallel with the arms 23 of the frame 22. Extending between the frame members 2 f, near the lower ends thereof, is a ledge or shelf 29, the ends of which extend beyond the frame members and ngage with the links 27 and 28 to limit the rearward the frame 22 is swung into its exterior posi-- tion, asclearly shown in Fig. 2. A holding or display tray 32 rests on the ledge or shelf and is retained in position on the frame 22 by clips'33, or in any other suitable manner.

' The usual receptacle for holding the sterilizing solution is placed within the cabinet, and when the articles to be sterilized are placed in the tray 32 the mechanism above described is pushed into the cabinet into the position shown in full lines in Fig. 2, and the doors 15 closed. The articles in the tray may be readily inspected in this position, and when it is desired to use the same, the doors are opened and the frame 22, carrying the tray 32, is pulled forward into the position shown in dotted lines in Fig. 2. As the pivot points of the frame members 23 and of the links 27 and 28 lie in parallel planes, the frame 22 has the well known parallel motion, with the result that the tray is always held in the same angular position, with respect to the perpendicular, whetherin the cabinet or exterior thereto.

While I have shown and described the preferred embodiment of my invention, it is plurality of parallelly arranged arms piv-- otally mounted on said brackets, a frame, carrying an. instrument" tray, pivotally mounted at the top of said plurality of parallelly arranged arms andcapable of being moved into and out of the cabinet in a constant angular position to the perpendicular, means on said frame for engaging with a pair of the plurality of parallelly arranged arms to limit the outward movement of the frame, and a ledge on said frame for holding a display tray and for limiting the inward movement of said frame.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
